Typical Properties (4) of Post cured (5) Resin Clear Casting:
Typical property values only, not to be construed as specifications.
Cure schedule: 24 hours at room temperature; 3 hours at 85°C (185°F)
Maximum stress: 1.8 MPa.
Test specimen must be prepared by mold.

Handling and Storage Consideration:
This resin should be stored indoors in the original, unopened and undamaged packaging, in a dry place at temperatures between 5°C and 30°C. The shelf life of styrene containing unsaturated polyester resins will be significantly reduced when exposed to light and/or higher temperatures.

This resin contains ingredients which could be harmful if mishandled. Contact with skin and eyes should be avoided and necessary protective equipment and clothing should be worn.
